Oh my yes! Enlarged uterus' is very common. But it is not your only option by any means.
You could try D&C w/hysteroscopy and/or endometrial ablation; myomectomy if you have fibroids; an IUD (I'm having one inserted next month)..birth control pills; UAE (uterine artery embolization).
Please investigate all options before you make such an irreversable decision.
I had the talk yesterday with my gyn regarding the same thing. My uterus is way too large for the ablation he tried. I'm 50 and have pretty much exhausted all options except the IUD...even my doctor wants me to hold off for as long as I can because I'm so close to the change...but with no symptoms yet.
Best of luck, and like I said...investigate all and I mean, all your options first!
